Interdependência entre proporcionalidade e o ensino de educação financeira e funções

Abstract

This work documents the development of a virtual and interactive educational resource consisting of activities on proportionality in the context of financial mathematics, with the aim of promoting the development of logical reasoning, problem-solving skills, and the construction of mathematical knowledge through the analysis of patterns and regularities. The activities were organized in light of Bloom’s Taxonomy. Throughout its development, the concepts of ratio and proportionality are investigated from historical, conceptual, and applied perspectives, establishing connections with the study of functions and with financial education in basic education. The choice of this theme is justified based on the guidelines of the Brazilian National Common Core Curriculum (BNCC), which emphasizes the development of proportional reasoning, mathematical modeling, and financial education as essential competencies for students’ critical and civic formation. The educational resource is available at: <https://flaviacerqueiracezar.github.io/Proporcionalidade_Educacao_Financeira/> As an educational product, a set of financial education activities was developed and organized in an online and interactive environment, allowing students to explore realistic situations, test hypotheses, analyze graphs, and interpret results. These activities aim to promote meaningful learning by articulating mathematical concepts, informed decision-making, and financial literacy, in accordance with the competencies and skills established by the BNCC.
